ABSTRACT

A package for flowable cement is provided which includes a carton having a pair of generally conical-shaped cement containers located therewithin.

Flowable cement, in particular roofing cement, has generally been sold in pint and quart size cans or in caulking tubes which are cylindrical in shape and formed of fiberboard with metal rims. Dispensing of the roofing cement from metal cans is relatively difficult as it requires that an element be dipped into the can and the cement be retrieved therefrom and placed where desired. Utilizing a caulking tube provides simpler placement of the roofing cement, but detrimentally requires that the operator also utilize a caulking gun in order to dispense the cement.

I have devised a completely self-contained unit which contains no metal parts and permits disposal in a manner that is ecologically beneficial. Further, my invention obviates the use of metal cans, caulking tubes and caulking guns and permits the roofing cement to be dispensed in a very simple and efficient manner.

It is an object of the present invention to provide a flowable cement container that permits easy dispensmg.

It is a further object of the present invention to alleviate the litter that is associated with prior art cement containers by providing a container that is completely formed of plastic material and includes no metal parts.

Another object of the present invention is to provide a complete self-contained unit which enables the purchaser to utilize the roofing cement contained in the package of the present invention without the need to I purchase additional materials, such as a caulking gun.

A still further object of the present invention is to provide a self-contained flowable cement package that is relatively inexpensive to produce and provides a very efficient container.

Other details and advantages of the present invention will become apparent from the following description, claims and accompanying drawing.

BRIEF DESCRIPTION OF THE INVENTION In accordance with the present invention, there is provided a container for cement in flowable form which comprises a generally conical-shaped container formed entirely of flexible plastic sheet material and having heat-sealed peripheral portions to prevent release of the cement from the container until the cement-carrying portion of the container adjacent the apex of the cone is severed. The plastic sheet material has enough flexibility to permit manual squeezing of the container to release the cement therefrom after severance thereof.

In the illustrative embodiment, a package is provided for holding a pair of the above-mentioned cement containers. The package comprises a carton in the form of a rectangular parallelepiped having a pair of the conical-shaped cement containers located therewithin. The containers fill a major portion of the carton, with the apex of one container being located adjacent the base of the other container to form an assembly of containers having a generally rectangular outline substantially conforming in shape to the outline of the package.

A more detailed explanation of the invention is provided in the following description and claims, and is illustrated in the accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of a package for flowable cement constructed in accordance with the principles of the present invention;

FIG. 2 is a front view thereof, with the front of the package removed in order to present a view of the inside of the package;

FIG. 3 is a flowable cement container constructed in accordance with the principles of the present invention, with some of the cement being forced out of the container; and

FIG. 4 is a cross-sectional view of the cement container of FIG. 3, taken along the line 44 of FIG. 3.

DETAILED DESCRIPTION OF THE .ILLUSTRATIVE EMBODIMENT Referring to FIG. 1, there is shown a package for roofing cement or the like comprising a carton 10 formed of cardboard or the like in the shape of a rectangular parallelepiped having ends 12, 14 which are folded in the conventional manner so as to permit the removal of the contents from carton 10 by unfolding either end 12 or 14.

A pair of cement containers l6, l8 and a plastic trowel 20 are positioned within carton 10. Containers l6 and 18 are identical and are illustrated in detail in FIGS. 2-4. Each container is generally conical-shaped in configuration and formed entirely of flexible plastic sheet material, such as polyethylene, having heatsealed peripheral portions 22, 24, 26 and 28 to prevent release of the cement 29 from the container.

In forming containers l6, 18, a first sheet of laminated plastic material is laid upon another sheet of the same material. A number of continuous, generally conical-shaped heat seals are provided adjacent to each other to form sides 24, 26 and apex 28 of a number of conical-shaped members. The sheets are severed along lines substantially parallelto the heat seal on the outside thereof to form generally conical-shaped containers that are heat-sealed at the sides and apex, but are open at the base 22.

A flowable cement, such as roofing cement, e.g., Sherman Williams Plastic Roof Cement or Montgomery Wards WET AND DRY Roof Cement, is then introduced into the containers through the base and the base is then heat-sealed in a line which intersects the heat seals 31, 33 defining the sides of the cone. Two identical containers are placed in carton 10 with the base 22 of one container lying adjacent the apex 28 of the other container, as shown in FIGS. 1 and 2. It can be seen that the assembly of two containers will have a generally rectangular outline substantially conforming in shape to the outline of carton l0.

To apply the cement, containers l6 and 18 are removed from carton l0 and the container to be used is severed along a line 36 (FIG. 3) which is on the side of the apex heat seal 34 toward base 22. The plastic sheet material utilized to form containers l6 and l8 is flexi- Although an illustrative embodiment of the invention has been shown and described, it is to be understood that various modifications and substitutions may be made by those skilled in the art without departing from the novel spirit and scope of the present invention.

What is claimed is:

1. A package containing flowable cement which comprises a carton formed of cardboard in the form of a rectangular parallelepiped having a major plane and a minor plane and having positioned therewithin a plurality of generally conical-shaped cement containers, said containers being formed front two plastic sheets which are heat sealed together to provide a seal about the entire periphery of said formed container to prevent release of the cement from the container until the cement-carrying porton of the container adjacent to the apex of the cone is severed, said plastic sheet material having enough flexibility to permit manual squeezing of the container to release the cement therefrom after said severance, said containers filling a substantial portion of said carton with the apex of one container being located adjacent the base of the other container along the major plane of said carton to form an assembly of containers having a generally rectangular outline substantially conforming in shape to the outline of said package, and further including a trowel positionedin said carton with said plurality of cement containers.
